IMPROVEID MACHINE FOR 1".A.RR`.II13"G` 'PAPER FOR ROOI'ING, cc.

The Schedule'refen'ed to in these Letters Patent and making part-'of thesame.

To all whom. it 'may concern Be it known that I, JOHIN ROBERTS, ofValthain, in the county 0f Middlesex, and State of Massachusetts, haveinvented certain Improvements in Machines for larring Paper for RoongPurposes, of which the following is a specification, reference being hadto the accompanying drawings.

My invention consists in the novel construction, arrangement, andcombination of certain mechanical devices in a rna'chine for satura'tiugpaper with coal tar, or any other substance or substances for rootingpurposes, in such ainauner that the paper may be thoroughly andconveniently saturated bya single operator, as hereinafter explained. 4

In the drawings- Figure l is a longitudinal vertical section of mymachine, complete, and

Figures 2, 3, and 4 are views of parts detached, and Figure 5 is across-section ou the line a.' x, ot'iig. 4.`

In constructing my,` machine, I make a suitable frame, A, of any sizedesired, and in Open bearings.

At the upper ends of uprights C, at one end ot' this frame, mount aroller, I), havinga loose collar, a, 'as shown in dotted lines in vtig.2, and detached in fig.`3.

In the opposite end of the frame, I mount a drying friction-roller,I,bound with cord b, or other material suitable for the purpose,hereinafter explained.

Above the roller I, which is mounted in the uprights B, I mount thesword or split-roller E, in Open bearings, so that it may beconveniently removed.

In the same'iialne A, I also mount press-rollers F and G, in bearings cand d, arranged so as to be ad- `instable by setscrews e and f, and tobe held in position by levers J, pivoted so as to allow these rollers tobe removed, all as clearly shown in tig. 1.

The rollers F and Gare provided with gear-wheels, and are connected witha gear-wheel On the roller I, by an intermediate gear-wheel K, as shownin the same ligure.

Between the roller G and the upright C, I place a frame, H, so arrangedas to slide vertically, in suitable `slots or guides attached to or inthe sides of the frame A, and having connected to the lower end of eachVof its sides curved pieces L, in which are three rollers, y, h, and i,and having 'its sides provided with holes It', for setting it atdiiierent heights, as desired.

In operating my machine, thus constructed, I placeit over anyreceptacle, M, suitable for receiving the coaltar, or other substanceVto be heated, and with which the paper is to `be saturated, in such amanner that the frame H may carry its rollers g, h, and t into theliquid, and also, so that the drippings from the pressure rollers orother parts of the machine may fall into it. lVhen the liquid issufficiently heated I take out the roller I), remove its collar a, slideonto it a roll of paper, N, return the collar a, and replace the rollerD,

with the roll of paper upon it, in its bearings in the upright C. I thenpass the loose end' of the paper under the Vrollers in the lower ends ofthe frame H,

up through between the pressure-rollers I" and G, andconnect it to .heswordrol1er E, bypassing it between the two parts of this roller, andlocking it there. 'As this roller isA divided diagonally, as shown in g.4, they are fastened together by having their thin ends enter a recess,y, under the collars of the roller, as

shown in figs. 4' and 5. f

When this is done, the machine is adjusted by setting the frame H andthe rollers F and G as desired, then by means of a 'single crank, 0,att-ached to the end of the roller I, the whole machine is operated.

The roller I, by means of friction, simply causes the rollerE to turnand receive the paper, while, by means of the gearing, the pressurerollers are operated, and these in turn draw the paper through the hotliquid, around the lower end of the frame H.

The advantages of this machine over those now in i use are many. Thepaper is rst easily mounted upon convenience in introducing'the paper,and are adjust-v able, so as to suit the pressure to the thickness ot'the paper, or to the character ofthe saturatiug'liquid. rlhe cord, orother material, bound about theroller I serves both to increase itsfriction and to dry the paper.

VBesides these advantages, the machine may be operated by a singleperson, and by a` single crank.

I am aware that machines have been made for drawing paper from one rollonto another, through saturating liquids, about -a single.vertically-adjustable roller in the liquid, and then on through guiderolls and over Scrapers. Having filed an application for a patent for amachine containing these devices, substantially', on the 8th of June,1847, as will be seen bya reference to the recordsot' the Patent Olice,and having used and experimented with such machines from that time tothepresent, and therefore, I do not claim such a machine, broadly; but whatI do claim, 1S

1. A machine for saturating paper for roong pui`` poses, consisting ot'a frame A, having mounted therein the rollers I), verticallyfadjustableframe H, pro- `vided with therollers g, h, and 1", the movable and ad-4. In combination', the movable roller D, provided with loose collar a,the vertically-adjustable frame H, with the rollers g, h, and i mountedin its end-pieces Q. The movable and adjustable pressure-rollers F L,and the sword or split-roller E, constructed andarand G, with theirloose bearings e and d, when conranged to operate as described, and forthe purpose structed and arranged substantially as herein described, setfort-h. and for the purpose set forth.

jnstable rollers F and G, and rollers I and E, all constructed andarrangedw to operate as herein described.
